Data transmission network technology is key link of realizing safe and high-efficient gathering production of coal-bed gas. The paper introduced gathering process of coal-bed gas like neural networks and its characteristics, indicated requirements of gathering process of coal-bed gas to data transmission network technology. Through analyzing existed problems of current data transmission technologies namely transmission network based on wired media, wireless network based on GPRS and wireless network based on 3G applied in gathering process of coal-bed gas, the paper proposed a self-built wireless network framework which is suitable for characteristics of gathering process of coal-bed gas and analyzed its technical advantages. It indicated that the framework could provide an effective data transmission mean for safe and high-efficient gathering of coal-bed gas.
